Patent CA-2293512-A1 (CA)
Inventor: NAVA ADRIANO
IPC: H04B10/294
Filed: 1999-12-29
Abstract: An optical communication system and method for starting up and shutting down the system to ensure safety during repair of a fiber break are disclosed. A technique for shutting down an optical communication system having spans of optical transmission fiber interspersed serially between optical transformation sites and a plurality of amplifier sites includes shutting down both amplifiers on either side of a fiber disruption and both amplifiers in the same amplifier sites serving transmission in an opposite direction, followed by deactivation of all amplifiers within the same optical line between optical transformation sites. During startup, amplifiers enter an operating mode to ignore a system shutdown signal, an amplifier at a terminal site is forced on, and then successive amplifiers step through an intermediate safe power level before reaching full operating power.
Patent CA-2296921-A1 (CA)
Title: A large combined broadband and narrowband switch
Inventor: ZOLA MEYER JOSEPH
IPC: H04L29/06
Filed: 2000-01-21
Abstract: Apparatus, and a method for switching digital signals of different protocols in a large switching network. Signals and different protocols are encapsulated in a common protocol by a set of input modules. The signals in the common protocol are then switched by a large central stages to a plurality of output modules, which then generate signals in the correct protocol.      Narrow-band signals are converted into broadband signals, so that the central stage switches only broadband signals.      This simplifies the design of the central stage, while still making it possible to have a very large and economical central stage switch. Advantageously, this arrangement allows a single large switch to switch large quantities of traffic in a plurality of protocols.
Patent CA-2300449-A1 (CA)
Inventor: FARMINE YANN
IPC: H04L27/26
Filed: 2000-03-10
Abstract: Antenna weights for a transmit path (3) between two communication devices (1, 2), the first device (1) having an antenna array (4, 5, 6) are generated in the second device (2) and fed back to weighting circuitry (9, 10, 11, 12) in the first device (1). The invention is particularly applicable to multicarrier systems such as OFDM systems. Only weights for those sub--carriers identified as being received with comparatively poor signal quality are calculated and fed back to the first device (1), thus limiting the additional overhead requirements to a minimum.

Title: Materials handling vehicle having an expanded operator's compartment
Inventor: HENSHAW ROBERT J
IPC: B66F9/075
Filed: 1998-08-26
Abstract: The motor compartment (400) of a fork lift truck (10) is modified so that the operator's feet extend into the space normally required by the motor compartment. A motor support structure (430) is installed between the traction motor (410) and the gear box (440) which is connected to the steerable, powered wheel (25). The motor support structure occupies a smaller space than the traction motor itself, thus increasing the space available to the operator's compartment (70), at least in a limited vertical location adjacent to the support. With the traction motor out of the way, sufficient space for elevated pedals (130, 135, 140) is provided, thus providing the operator (200) ample space to operate the truck while seated. A battery compartment (20) and hydraulic system (500, 505, 510, 515) of the truck are positioned adjacent to one another and ahead of the operator's compartment/motor compartment. In this way, the battery compartment and hydraulic system are positioned such that they are clear of the operator's compartment.
